The International Navigation Conference 2015 marked the return of the Royal Institute of Navigation to the business of organising major navigation meetings. For some years they have waited on the sidelines as too many conferences competed for a declining number of delegates….

Approaching river locks, passing under bridges, and approaching riverside berths and ports were identified as the situations at inland waterway transportation with the highest risk with respect to the collisions with surrounding infrastructure [1]. The first one is the…

The Automatic Identification System (AIS) is an autonomous and continuous broadcast system that exchanges maritime safety/security information between participating vessels and shore stations. In addition to providing a means for maritime administrations

Collaborative navigation enables multi-sensory robust navigation, including seamless transition between different types of environments (see e.g. [1, 3]). In this concept several users and platforms (including pedestrians, vehicles and UAV’s) are equipped with different…

Side scan sonars are widely used for objects detection in seabed clearance investigations. Multibeam data about bathymetry and backscatter may be not enough in terms of detecting small objects, possibly dangerous for navigation…

The new IMO Sub Committee on Navigation, Communications Search & Rescue considers the Strategy Implementation Plan for e-Navigation at its meeting in July 2014 (NCSR1). The e-Navigation solutions embodied in that Plan depend on reliable, robust positioning…

Satellite navigation relies on the visibility of a sufficient number of satellites. As the number of satellites increases, some problems such as shadowing in urban areas are reduced although not completely removed. In other instances, such as in tunnels, positioning by satellites is not possible.

The European Geostationary Navigation Overlay Service (EGNOS) is Europe’s first venture into satellite navigation, providing an augmentation signal to the Global Positioning System (GPS) Standard Positioning Service (SPS). It has been a long way for Europe, since the beginning of the EGNOS programme in the late 90’s, culminated with the declaration of availability of the three EGNOS Services:
